1. VENTILATION & EXHAUST used for

 

Exhaust of toxic waste air
paint vapours, alcohol vapours , glues & adhesives vapours, combustion vapours, chemical toxic corrosive vapours dejection emissions, smoke, auto emissions etc.

Exhaust of the air wasted with small particles
dust, ash, rubber powder, plastic powder, cemment powder, wood powder, paper powder, flour, detergents, washing powder, mines stone powder, carbon powder, medical powder etc

Exhaust of the heating gases
hot air, combustion gases, hot gases etc

 

2. PASSIVE NOISE REDUCTION DEVICES used for

 

Industrial high pressure escapes used to reduce noise of an air and steam pressure comming out from pressure tanks,

High pressure jet in order to reduce the noise level

Combustion engine in order to reduce the noise level, but having a good amelioration of the output power of the engine

 

3. VACUUM CLEANER & ASPIRATOR used for

 

Rising and loading-unloading agricultural seeds

Vacuum systems for dust, sand & gravel, leafs and snow from parks and walking roads.

 

 

 

HIGH FLOW INDUCED WITH NO MECHANICAL MOVING PARTS

Coanda Nozzles are fluidic transformers, similar to the electrical transformers, that are supplied by high pressure & lower flow in order to get lower pressure & high induced flow.
The input flow is supplied by a fan, blower, other supersonic ejector, compressor or a steam tank.
Coanda divergent wall is generating up to 90% vacuum, over a very small surface named “Coanda lip”, therefore the high flow having low pressure are induced by the Coanda ejector without any mechanical moving parts such propeller, fan, blower or other blade devices.

HOW COANDA EJECTOR WORKS

Coanda ejector is a geometric device, having no moving parts, that create an induced flow using an input fluid flow coming from high velocity fluid device.
The common working fluid is air.
The Coanda ejector (yellow) is coupled to an existing diameter flow duct.
As soon as the ejector is powered on, a vaccum is created (red zone) and an induced flow appear.

WORKING PARAMETERS

Aerodin Coanda ejectors are designed in any configuration in order to induce any flow.
In order to have an industrial use we may provide any configuration working on standard ducts having diameters: 63, 80, 100, 125, 160, 200, 250, 315, 400, 500, 630, 800, 1000, 1250mm and more.

The flow amplification depends of the working configuration.

General ejectors series diagram //flow [m3/h] vs pressure [Pa]//, are presented as follows:

Coanda ejectors (yellow) may be used as a pusher or as a sucction device in a duct system.

Depending of the duct size, flow, suction pressure and the geometric design, the ejector may work single or in group of 4th, 16th or 64th ejectors.
